PERPETUAL CALENDAR AND OFFICE-TICKLER.

SPECIFICATION forming part of Letters Patent No. 792,641, dated June 20,1905. Application led January 15, 1904. Serial No. 189,196.

To all whom, it may concern.-

Be it known that I, CHARLES T. WTLBER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPerpetual Calendars and Cflice-Ticklers; and I do hereby declare thefollowing to be a full, clear, Y and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to a perpetual calendar and ofIice-ticklercomposed of guide-cards indexed to the month-day and week-days, theformer numerically and the latter in series also Yto the same, incombination with a series of daily index-cards arranged numerically tocorrespond with the month-days and in series with the week-days, so thatall weekly divisions or series of days of the indicating-calendar arearranged in easily-identified series in the monthly numerical divisions.

My invention further relates to the combination of month-cards with thedays thereof arranged in proper numerical series with an accompanyingindex whereby the cards may be readily identified to apply them to theproper month or months for a term of years,

and further relates to means whereby regardl less of the fact that anyparticular card may contain more than the required quota of day- Yindicating numbers (or an excess of days) for a certain month or aplurality of months the said card is adapted for use as an indicator fora month containing a less number of days.

The object of the invention is to produce a device which may be used asa so-called perpetual calendar which may be used for a term of years, inconjunction with means whereby removable and interchangeablememorandum-cards are provided corresponding to the months and days of amonth, said latter cards being numerically arranged and provided withindicating-tags corresponding with the days of the weeks in series ofsevens.

The invention consists in certainv novel constructions, combinations,and arrangements of parts, as will be hereinafter described andspecifically claimed.

In the drawings, Figure 1 is a perspective view of my improved device. yFig. 2 is a sectional view thereof; Fig. 3, a rearview of a column-card;Fig. 4, a vertical sectional view showing a modification; Figs. 5 and 6,fragmentary views of column-cards hereinafter referred to.

In the subjoin'ed description of my invention and in the claims in someinstances parts thereof will be referred to by arbitrary titles forconvenience in distinguishing them and to promote brevity ofdescription, as follows: month-cards l, those upon which the names ofthe months appear; column-cards 2,

' those upon which-appear the names of or abe breviations for the daysof the week, with numbers in series of seven arranged in conjunctiontherewith; day-cards 3, the series of separate cards, each of whichcarries an indicating-number arranged numerically in series of seven inline with the names of the days upon the column-cards; smonthly-indexcards 4, those cards of relatively large size, upon which the names ofthe months appear, which cards are designed to be used as partitions orseparating means between which matter relating broadly tomonth-divisions is to be temporarily placed to be afterward sorted andplaced between the proper day-cards. Daily index will b'e understood tomean the names of the days of the week or the commonly-usedabbreviations therefor.

First to be considered are the column-cards 2. These cards are allarranged with thirtyone numbers thereon arranged horizontally,numerically, and vertically in series of sevens, said numbers in eachcase appearing in at least four parallel longitudinal full rows, andcommencing with the uppermost number line there will appear sevennumbers from l to 7 both inclusive. In the second row will appear sevenadditional numbers 8 to 14, inclusive. The two next rows contain eachseven numbers consecutively arranged, and the last or bottom row has thenumbers 29, 30, anc 31 therein. Above the numbers on each card appearthe names of the days of the week or the customary abbreviationstherefor. On one card appear the names of the week commencing withSunday and terminatlng with Saturday, and each suc- IOO quota of sevenday-names. It will be apparent that seven column-cards are to be used inthe device, and .ineach1the1numbers are .con-1 secutively arranged underdifferent introductory days, commencing with No. l in each instance.Owing to the established calendar' division of days it is evident-thattheiirstday oi' a month occurs in coincidence with a-'parf .-Iticu-larday, as:lVIonday,.f.-in some instances more-than once inafgivenyeanfandi suchy arrangementvaries from year-to year. wInconv'sequence-.of this the column-.card herewith four upper rows to themonth of February illustrated in Fig. 1 is-applicableas to. its'.

.. r and August in 19011, toMay in71905-,to Janu- .iary and October in1906, and thus continuing existenceof the vcalendar itself. .Howevenasthe month of February, 1904,this being a leap-year,containstwenty-nine daysinstead `I ofxthe vfull thirtyonefprinteduonthefcard-,y exhibit of ffthe drawing, ar month card ofA bers 30 and 31..This month-card is in? proper contour is usedin conjunction withit-he 11 terposed between! thelcolumn-card anduthe observer, as shown innthedrawing, :therebykexposing twenty-nine day-numbeu only. -(Seei Fig. 1.)For February of all years butleapyearsnthe Februarymonth.- card'- will-Ibel so formed as to :coverthexnumbers 929, 30,?

As theday-numbers of all months'beginat 1:on the column-cards, it

is evident that the Vertical reading of the column-cards andlongitudinal reading of the 4day-cardsmustcorrespond.
